In the first case, which occurred in the early hours of July 4th, Capt. Lee Eckler of TowBoatUS Tarpon Springs, FL, received a dispatch from the BoatUS 24-hour call center indicating a mariner was summoning towboat assistance from a location 25 miles offshore of Anclote Key — far beyond cell phone range. With the SPOT and BoatUS partnership, Capt. Eckler was immediately provided with precise GPS coordinates as well as name, contact information, type and color of boat, which was identified as a 17-foot center console. Upon arrival on scene, he found three anglers with a dead engine “loaded for fishing,” said Eckler.
